Put it more clearly that most bug reports without an email address are useless

Our Report an error page reads:

Giving us an email address allows us to contact you to clarify the problem. But it also provides an opportunity for eavesdroppers, like your email or Internet provider, to confirm that you are using Tails.

The WhisperBack UI reads:

If you don’t mind disclosing some bits of your identity to Tails developers, you can provide an email address to let us ask more details about the bug. Additionally entering a public PGP key enables us to encrypt such future communication.

Anyone who can see this reply will probably infer you are a Tails user. Time to wonder how much you trust your Internet and mailbox providers?

I think it would be good to put it very clearly that most bug reports we receive, that lack an email address, are basically useless.
(And by the way, I would remove the “Time to wonder..” part, that feels a bit too defensive to me.)
